鱼道紊流特性研究进展
Research Progress on Turbulence Characteristics of Fishway
摘要
Abstract
Turbulence characteristics in fishway are important for fish migration towards the upstream reach.In this article,we made a review on the research progresses of turbulence parameters including turbulence velocity,turbulent kinetic energy,turbulence intensity,Reynolds shear stress,and vortex in Danilian fishway,vertical slot fishway,composite fishway and culvert fishway.We also analyzed the rules and characteristics of turbulence distribution in different types of fishway,and pointed out that turbulence intensity and turbulent kinetic energy have great impact on habitat selection and fish passage.Finally we recommend conducting in-depth research on the turbulence characteristics of vortexes in fishway,which has received few research attentions,to improve the hydraulic condition in fishway and ensure an efficient operation.关键词
